853,118 professionals have used our research since 2012.
What do I think about the stability of the solution?
We haven't had any downtime in the years we've been using this product. We also have disaster recovery setups but haven't needed them.
What do I think about the scalability of the solution?
Scalability is pretty good, we have over 100 plus users, and inherently all our applications interact with S3. We use it heavily, it's our main storage medium.
How are customer service and support?
The tech support is very good. We had some help with the configuration and some of our niche use cases and more complex aspects of the implementation. Apart from that, we've rarely needed any S3 support because the UI and the functionality itself are straightforward so you don't need to go beyond the standard documentation provided.
Which solution did I use previously and why did I switch?
We're a small organization and previously had an on-prem solution that was more expensive for us with a lot of overheads. It didn't make sense to continue using it.
How was the initial setup?
It's a simple deployment once you get the hang of it. We had two people managing the deployment. You can develop your own templates for repeated actions and automate repeat jobs. It's not complex. We're currently using more than 200 terabytes. We're using three different modes so we're using the solution extensively.
What's my experience with pricing, setup cost, and licensing?
We were able to reduce our licensing costs by exploring the different storage classes and different lifecycle management policies. It's a very good tool to control your costs and automate a few of the routine tasks which typically take significant manual effort when you need to write ad-hoc jobs. The storage is quite cheap although there are some processes that bump up the cost.
Which deployment model are you using for this solution?

Beneficial automation, useful CLI, and simple implementation
Pros and Cons
- "Amazon S3 is easy to use and it is beneficial to use the CLI to make the backups. Since I use the CLI I do not have to do it on a web portal which is a big advantage because everything can be automatized. Automation can be done very well in Amazon S3."
- "The solution could improve by having a simpler way to have the detail size of a file in the CLI to be read or understood easier. Today, it's a little raw in the way the details are presented. You have to make some scripts and some modifications to be able to see the information properly of the size of a given bucket or the size of a file."
What is our primary use case?
I use Amazon S3 mainly for daily backups of our database.
How has it helped my organization?
Amazon S3 has helped our organization because the daily backups can be done automatically with automation. We do not have to spend time on it and I am confident with Amazon S3 in its ability to recover our data.
What is most valuable?
Amazon S3 is easy to use and it is beneficial to use the CLI to make the backups. Since I use the CLI I do not have to do it on a web portal which is a big advantage because everything can be automatized. Automation can be done very well in Amazon S3.
What needs improvement?
The solution could improve by having a simpler way to have the detail size of a file in the CLI to be read or understood easier. Today, it's a little raw in the way the details are presented. You have to make some scripts and some modifications to be able to see the information properly of the size of a given bucket or the size of a file.
For how long have I used the solution?
I have been using Amazon S3 for a long time. I used the latest version because the CLI is normally updated.
What do I think about the stability of the solution?
The stability of the Amazon S3 is good.
What do I think about the scalability of the solution?
The scalability of Amazon S3 is great.
We are a small company and we have approximately five developers that use Amazon S3. We use the solution on a daily basis for hourly backups.
How are customer service and support?
I have used the support from Amazon S3 a long time ago, I have not needed much help. When I did have contact with them there were times it took a while for a response.
I would rate the technical support of Amazon S3 a three out of five.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
The main difference from other solutions I have used is Amazon is the leader, and it has a very large number of zones and capacity, while others can be smaller and can have different options. Not all the options that are available in Amazon S3 are offered by other competitors, but for the main features, most of them are working fine. I have been evaluating two different solutions, one from a French cloud-based company called Scaleway, and the other is peer-to-peer storage.
How was the initial setup?
The installation was simple. Creating a new bucket and deploying it is very straightforward. To make the script deploy a new bucket takes approximately one hour.
I would rate the initial setup of Amazon S3 a four out of five.
What about the implementation team?
We did the implementation ourselves and we have two developers that do the maintenance of the solution.
What was our ROI?
The return on investment has been very good because the backups of our database are critical for our business to operate.
I would rate the return on investment of Amazon S3 a four out of five.
What's my experience with pricing, setup cost, and licensing?
The price of the Amazon S3 is reasonable. There are not any licensing costs, they have a pay-as-you-use model.
When backups are more than 6 months old, I would recommend keeping less of them and storing the remaining ones in Glacier (long-term, cheaper storage).
Which other solutions did I evaluate?
I have evaluated other options.
What other advice do I have?
My advice to others is to separate the buckets project, not to put everything in the same bucket, and be sure to implement IAM rules to avoid problems between users and not to lose any backups. The implementation process is important.
I rate Amazon S3 an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

- "The product is easy to use."
- "The product should enable users to create their own shortcuts."
What is our primary use case?
We are using the solution to host our website and manage the database.
What is most valuable?
We have an online portal, and we are providing services to customers. We need to maintain an elastic database storage, along with security features. The solution’s functionality and accessibility are valuable to us. It's geared towards users. It makes things simple. The product is easy to use.
What needs improvement?
The product should enable users to create their own shortcuts. It should allow more customization. Users should be able to place their shortcuts on the dashboard. It will make things easier.

What other advice do I have?
For disaster recovery, there's a backup going on in AWS. At the same time, we take our own local backup. It is a daily process. People who want to use the solution must explore the tool and look at the training videos. It is quite straightforward.
We have a subscription model with our customers. They pay it yearly. There are no additional costs associated with the product. We had a problem with storage when we were working with on-premise servers. The hard disks were failing because of the volume of the data. They were regularly failing every three to four months. There was a cost associated with it. It impacted our project.
Overall, I rate the tool a ten out of ten.

Excellent features, hearty scalability, with varied use cases that fit almost any client
Pros and Cons
- "The most valuable feature is the automated replication of the data."
- "I would like to see the API for beginners improved because it is hard to understand."
What is our primary use case?
We are very flexible with our use cases and it fits most clients.
What is most valuable?
The most valuable feature is the automated replication of the data. You can store things and they automatically replicate somewhere else. So if you have an issue, you have a backup, and that is very good. You can set up how often you want it backed up, and I find that extremely useful.
What needs improvement?
I would like to see the API for beginners improved because it is hard to understand. It is based on the idea of a container when most programmers just understand directories and subdirectories. For a beginner, the API is a bit confusing.
For how long have I used the solution?
I have been working with Amazon S3 for the past four years
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The scalability is definitely present from hundreds to thousands depending on the client.
Which solution did I use previously and why did I switch?
I have used other solutions in the past, but none of them are as scalable.
How was the initial setup?
The initial setup If you have the experience is fairly simple. If you do not, then it is fairly complex.
What's my experience with pricing, setup cost, and licensing?
I know it is very inexpensive compared to other solutions.
What other advice do I have?
I would basically recommend that individuals just follow the guidelines AWS as they are very good. I would rate Amazon S3 an eight on a scale of one to ten.
Which deployment model are you using for this solution?

Is stable, scalable, and has multiple types of data detection
Pros and Cons
- "Amazon S3 has multiple types of data detection. You can store data on a monthly basis, yearly basis, and long term basis."
- "The only pain point is migrating the life cycle policy because if someone is a newbie, they cannot easily create the life cycle policy."
What is our primary use case?
We use it for static website hosting, storing data, and second data of some of the websites. We can then easily sync the data whenever we have the need to do so.
Some of our websites are 2 or 4 pages and have static content. We can simply host it by creating a bucket, putting the content of the website there, and making it available to the public with the Make Public feature.
What is most valuable?
Amazon S3 has multiple types of data detection. You can store data on a monthly basis, yearly basis, and long term basis. You can choose the Glacier feature, create a life cycle policy, and store it. This is one of the best features this solution has.
It is stable and scalable, and the installation is very straightforward as well.
What needs improvement?
The only pain point is migrating the life cycle policy because if someone is a newbie, they cannot easily create the life cycle policy. This is because there are multiple, additional ways. If I want to store data for one month, they have the option to Glacier over it. With Glacier, you have addition policies for one year or four years. The option will not be there. So you would need to use a UI process over it.
For how long have I used the solution?
I've been using it for almost the last four years.
What do I think about the stability of the solution?
I think the stability of Amazon S3 is good.
What do I think about the scalability of the solution?
It is scalable. We currently have 40 plus users.
How are customer service and technical support?
Amazon Protect Support has been been quite responsive.
How was the initial setup?
The initial setup was completely straightforward.
What's my experience with pricing, setup cost, and licensing?
The licensing is pay as you go, and I'm happy with the pricing.
Which other solutions did I evaluate?
We didn't evaluate other options because there's no such available feature in the market at present that can compare all the things in a bucket, like S3.
What other advice do I have?
If you are a small scale enterprise that wants to host websites or data, you should go for it and use Amazon S3.
I would rate Amazon S3 at nine on a scale from one to ten.
Which deployment model are you using for this solution?

What is our primary use case?
We use Amazon S3 for a file storing system. The solution is cloud-based.
We're working with 10-15 applications.
What is most valuable?
The most valuable feature is the sharing capabilities.
What needs improvement?
I would like there to be more support without needing to use Transfer Family.
For how long have I used the solution?
I have used Amazon S3 for about five years but not at my current organization.
What do I think about the stability of the solution?
I would rate the stability as eight out of ten.
What do I think about the scalability of the solution?
The scalability is good.
Which solution did I use previously and why did I switch?
I have also used Azure.
What's my experience with pricing, setup cost, and licensing?
The price is okay.
What other advice do I have?
I would rate this solution as nine out of ten.
I would recommend Amazon S3 if you have the use case for it, but Azure provides a similar service.
Which deployment model are you using for this solution?
Public Cloud
